Book Description
Dans cette thèse, nous avons utilisé la spectroscopie par Résonance Magnétique Nucléaire (RMN) in vitro pour l'étude de prélèvements cérébraux dans trois cas différents. La première partie constitue le travail principal de cette thèse. Elle a trait à l'analyse de biopsies de tumeurs cérébrales humaines par RMN 1H. Elle nous a permis d'établir des profils métaboliques caractéristiques de pathologies cérébrales. La deuxième partie est consacrée à l'étude de prélèvements cérébraux de brebis saines ou atteintes de tremblante. Ici aussi, nous avons pu établir des profils métaboliques caractéristiques de cette pathologie dans deux régions du cerveau. Dans une troisième partie, l'analyse par RMN 19F d'extraits cérébraux de rats traités au 5-fluorouracile (5-FU) nous a permis d'étudier le métabolisme de cet agent anticancéreux fluoré sur un modèle expérimental de gliome.

Book Description
Clinical Applications of MR Spectroscopy Edited by Suresh K. Mukherji, M.D. Magnetic resonance spectroscopy (MRS) is a powerful diagnostic tool for a variety of brain disorders—from epilepsy and tumors to age-related degeneration and strokes. Unlike magnetic resonance imaging (MRI), which gives us a picture of anatomical and physiological conditions, MRS generates a frequency domain spectrum that provides information about biochemical and metabolic processes occurring within tissues. Clinical Applications of MR Spectroscopy presents a short, practical treatment of MRS today. Comprising contributions by leading authorities in the field, the book discusses MRS techniques used for diagnostic purposes and research, terminologies and examples drawn from clinical experience, and ways to correlate MRS results with other modalities to enhance our understanding of disease processes and the outcomes of particular treatments. Topics include: Basic principles of clinical proton magnetic resonance spectroscopy MRS in the evaluation of epilepsy Proton MRS of brain tumors Proton MRS in selected childhood disorders MRS and spectroscopic imaging for cerebrovascular disease MRS of degenerative brain disease in the elderly MRS of the head and neck Potential clinical applications of new techniques in MRS Correlation of functional brain imaging with MRS Clinical Applications of MR Spectroscopy provides 150 photographs and figures to illustrate the interpretation of MRS signals, as well as fully referenced chapters for those wishing to expand their knowledge of the underlying science. It is an essential guide to the state of the art for radiologists and neurologists using this technology to improve patient care.

Book Description
This book examines the fundamental concepts of multimodality small-animal molecular imaging technologies and their numerous applications in biomedical research. Driven primarily by the widespread availability of various small-animal models of human diseases replicating accurately biological and biochemical processes in vivo, this is a relatively new yet rapidly expanding field that has excellent potential to become a powerful tool in biomedical research and drug development. In addition to being a powerful clinical tool, a number of imaging modalities including but not limited to CT, MRI, SPECT and PET are also used in small laboratory animal research to visualize and track certain molecular processes associated with diseases such as cancer, heart disease and neurological disorders in living small animal models of disease. In vivo small-animal imaging is playing a pivotal role in the scientific research paradigm enabling to understand human molecular biology and pathophysiology using, for instance, genetically engineered mice with spontaneous diseases that closely mimic human diseases.

Book Description
Thickening Fat: Fat Bodies, Intersectionality, and Social Justice seeks to explore the multiple, variable, and embodied experiences of fat oppression and fat activisms. Moving beyond an analysis of fat oppression as singular, this book will aim to unpack the volatility of fat—the mutability of fat embodiments as they correlate with other embodied subjectivities, and the threshold where fat begins to be reviled, celebrated, or amended. In addition, Thickening Fat explores the full range of intersectional and liminal analyses that push beyond the simple addition of two or more subjectivities, looking instead at the complex alchemy of layered and unstable markers of difference and privilege. Cognizant that the concept of intersectionality has been filled out in a plurality of ways, Thickening Fat poses critical questions around how to render analysis of fatness intersectional and to thicken up intersectionality, where intersectionality is attenuated to the shifting and composite and material dimensions to identity, rather than reduced to an “add difference and stir” approach. The chapters in this collection ask what happens when we operationalize intersectionality in fat scholarship and politics, and we position difference at the centre and start of inquiry.

Book Description
The invasive character of a primary cancer is greatly dependent on numerous interactions between tumor cells and their extracellular surroundings. Matricellular receptors are defined as (cell-surface) receptors that bind extracellular matrix (ECM) structural proteins and soluble factors dynamically acting on ECM homeostasis. Matricellular receptors mediate numerous signalings from the extracellular environment to cell nucleus and drive main biological functions that are cell growth, survival and migration. Numerous data from the last decade evidence that matricellular receptors are biosensors that allow to a tumor cell answering to microenvironmental variations, and in this sense they are important contributors to tumor cell malignancy. Matricellular receptors represent thus valuable targets for the development of original anti-cancer strategies. Original reports, bibliographic reviews or hypotheses are welcome to improve the basic knowledge of matricellular receptor properties, their spatio-temporal regulation, the dynamic formation of complex receptors and the impact of such interactions on the invasive properties of tumor cells. Biological, biophysical and pharmacological, as well as in silico contributions will be appreciated.

Book Description
This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.

Book Description
From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.
